I would like to see a new custom field type that allows for a set of labels to be applied. This would allow for Labels that are related to each other to be collected together while labels that may not be related to be in different columns.
For Example: a column with labels that are all types of fruit. As second column that allows for labels identifying locations.
Currently, if I search for the Apple label and California label, I will get All items with Apple (even if they don't have California) and all items with California (even if they don't have Apple), not items California and Apple. Having these separated would allow for better filtering.
We want to use labels for these types of categories because many views cannot be set up using Text Custom Field Filtering.
(These are just two random examples and there are many other ways labels could be grouped under different columns.)
